i wanted to make it a one liner, but i had to import modules :(

import sys, xml, urllib

dummy = [sys.stdout.write(city + ': ' + str(num) + '\n') for city, num in  
set([[(a, o.count(a)) for a in p] for o, p in [2*tuple([[city for city in  
((xml.dom.minidom.parseString(urllib.urlopen('http://api.etsy.com/feeds/xml_user_details.php?id='  
+ str(id)).read()).getElementsByTagName('city')[0].childNodes + [(lambda  
t: (setattr(t, 'data', 'no city'),  
t))(xml.dom.minidom.Text())[1]])[0].data.lower().replace('  ', ' ') for id  
in [71234, 71234, 71234, 71234, 71234, 71234, 42792])]])]][0])]
